The order is locked in
The list is committed as a hash chain: each link is blake2b-256(block ++ rest). Change one block or its position and the fingerprint no longer matches the policy.
Data is Beautiful · The mint
One block. One mint. In the order the chain made it.
Every Data is Beautiful NFT is a real Cardano block, painted by the Data Lab method and minted exactly once. Mainnet minting is not open yet. You can run the real mint engine on the Cardano preprod testnet today, with your own wallet.
Mainnet mint: not open
Preprod test mint: live
The engine
A list that can only be read forward.
Before a volume opens, its blocks are frozen into an ordered list, and the list's fingerprint goes into the minting policy itself. Each mint must reveal the next block on that list, mint exactly one copy, and move the cursor one step. Nothing can be skipped, repeated, added or minted twice. After the last block, the volume is closed for good.
02 · Mint
One reveal, one token
A single state token holds the cursor. Each mint spends it, proves the next link, mints one unit named by the block hash, and returns the state one step further.
03 · Close
Finite by construction
After the last link the state is terminal. The script refuses every further mint, so supply is fixed by code, not by promise. Holders can still burn their own token.
Replay the rules: a five-block volume
This panel runs the policy's rules in your browser against a five-block example volume. The transaction size, fee and script cost come from our recorded emulator run on 26 September 2026. Nothing here touches a blockchain.

Preprod test mint
Run the real engine with your own wallet.
This uses the same compiled policy on the Cardano preprod testnet. Your wallet is the only issuer and the only signer, and the test tokens land in your wallet. Test ADA has no value, and neither do these tokens.
1
Connect a wallet
Use a CIP-30 browser wallet set to preprod. Lace and Eternl, for example, can switch networks in their settings.

Need test ADA? Use the official Cardano testnet faucet and choose Preprod. You need at least 10 test ADA.
2
Choose your volume
Pick one to five Data Lab plates. The order you pick them in becomes the order the policy will enforce.
0 plates selected
3
Create the test collection
Creates the policy and its state token. The policy commits to your plates, their order, and your wallet as issuer.

Mint in order
Each mint reveals the next plate on your list. Your wallet will show the transaction before you sign.
Activity
- Connect a wallet to begin.
What the server sees: your change address, the wallet outputs your wallet shares for building, and the signed transaction to relay to preprod. It looks up chain data through the public Koios API, including the stake pool of a mainnet wallet you check. It never sees or stores a key or recovery phrase, and it keeps no record of your wallet. Transactions are built on simbapool.com because this site does not load third-party code.
Mainnet
What is decided, and what is not.
Nothing on this page is an offer to sell. When mainnet terms exist, this page will say so.
Built and tested
- One policy per volume, each committing to a fixed, ordered list of blocks.
- Exactly one token per block, named by the block's own hash.
- Closed after the last block; burning never re-opens supply.
- CIP-25 v2 metadata with raw-bytes keys, carried in every mint.
- 24 policy unit tests and 6 full-ledger emulator tests pass, including seven attack attempts.
Not decided yet
- Price, volume size and launch date.
- Custody of the issuer signing keys.
- Independent review of the policy script.
- Media storage and marketplace listing.
- Final art mapping for the collection.
Check a mainnet wallet
Connect a wallet on mainnet to see its balance and which stake pool it delegates to. Nothing is signed.
What you receive
Metadata you can check yourself.
Every mint carries its CIP-25 v2 record in the same transaction. This preview shows the shape for any Data Lab plate. The policy ID and final image location are set at launch.
Questions
Before you sign anything.
Can I buy a Data is Beautiful NFT today?
No. Mainnet minting is not open, and no price, supply or date has been announced. Anything claiming otherwise is not from us. The only official page is this one on simbapool.com.
Is the preprod test mint safe?
It runs on a test network where ADA has no value. Your wallet shows every transaction before you sign it, and only your wallet can sign. Never enter a recovery phrase on any website, including this one.
Why does my wallet need to be on preprod?
The test mint refuses mainnet addresses by design, so a mistake can never spend real ADA. Switch the network in your wallet's settings, then reconnect.
What does "in the order the chain made it" mean?
A volume's blocks are minted in the order they appear in its registry, which for the main collection follows block height. The policy enforces that order on chain.
Can the team mint extra copies later?
No. Once a volume's last block is minted, its policy rejects every further mint, including from us. A new volume needs a new policy with its own ID.
What happens if I burn my token?
It is destroyed. The block can never be minted again, because the policy's cursor only moves forward.
Where do I learn how Cardano NFTs work?
Read our Cardano NFT guide. It covers policies, metadata standards, costs, wallets, tooling, testing and a launch checklist.
Where the images come from
Each plate is drawn by the Data Lab from one block's own numbers. The method, the source blocks and their receipts are public.
